Pet turned nasty!

Lauren • 31, partner is 35. We have three children, William 10, Georgia 2 & Eliza just born. I work with domestic abuse victims in the north east of England. Partner is a roofer/joiner.

So we have had our cat for 5 and a half years now. And yes im not the biggest fan of cats, but ive always been good to our cat. He is absolutely not allowed in our sons bedroom and i dont let him on our bed. I feed him, give him treats, let him out. Not a lot you can do with cats really.

Hes never been a vicious cat, has been very good with kids but has always preferred my partner. I dont mind this 1 bit! He tried to bite my son once when my son was 2 and he is almost 7 now. Thats been the only other incident before now.

So im sitting on the couch catching up with tv and the cat is next to me. I stroke him normally and he bloody clamps down on my hand! Really goes for it as well. I was totally shocked!

Has anyones pets ever just turned before, is there a reason????
